ESLint-plugin-React
React specific linting rules for ESLint
Install ESLint either locally or globally. (Note that locally, per project, is strongly preferred). If you installed ESLint globally, you have to install React plugin globally too. Otherwise, install it locally. Use our preset to get reasonable defaults. If you are using the new JSX transform from React 17, extend react/jsx-runtime in your eslint config to disable the relevant rules. You should also specify settings that will be shared across all the plugin rules. If you do not use a preset you will need to specify individual rules and add extra configuration. This plugin exports a recommended configuration that enforces React good practices. This plugin also exports an all configuration that includes every available rule. This pairs well with the eslint:all rule. These configurations will import eslint-plugin-react and enable JSX in parser options. -

Gitrob
Scans GitHub repositories for potentially sensitive files
Gitrob is an open source reconnaissance tool designed to identify potentially sensitive files that have been committed to public GitHub repositories. It helps security professionals, researchers, and organizations detect accidental data exposure by scanning repositories associated with specific GitHub users or organizations. The tool works by cloning repositories and analyzing their commit history to search for files that match predefined signatures of sensitive data. These signatures are used to flag items such as credentials, private keys, configuration files, and other materials that may expose confidential information. By automatically inspecting repository histories, Gitrob simplifies the process of identifying security risks that might otherwise remain unnoticed in publicly accessible codebases. The results of the scan are presented through a built-in web interface that allows users to browse findings, review flagged files, and analyze potential leaks more efficiently. -

HSD
Handshake Daemon & full node
Handshake is a decentralized, permissionless naming protocol where every peer is validating and in charge of managing the root DNS naming zone with the goal of creating an alternative to existing Certificate Authorities and naming systems. Names on the internet (top level domains, social networking handles, etc.) ultimately rely upon centralized actors with full control over a system that are relied upon to be honest, as they are vulnerable to hacking, censorship, and corruption. Handshake aims to experiment with new ways the internet can be more secure, resilient, and socially useful with a peer-to-peer system validated by the network's participants. Handshake is an experiment that seeks to explore those new ways in which the necessary tools to build a more decentralized internet. Services on the internet have become more centralized beginning in the 1990s, but do not fulfill the original decentralized vision of the internet. -

Jest Puppeteer
Run your tests using Jest & Puppeteer
Most continuous integration platforms limit the number of threads one can use. If you have more than one test suite running puppeteer chances are that your test will timeout. This is because jest will try to run puppeteer in parallel and the CI platform won't be able to handle all the parallel jobs in time. A fix to this is to run your test serially when in a CI environment. Users have discovered that running test serially in such environments can render up to 50% of performance gains. Writing integration test can be done using Puppeteer API but it can be complicated and hard because API is not designed for testing. Debugging tests can be hard sometimes and it is very useful to be able to pause tests in order to inspect the browser. Jest Puppeteer exposes a method jestPuppeteer.debug() that suspends test execution and gives you the opportunity to see what's going on in the browser. -

Jimp
An image processing library written entirely in JavaScript for Node
An image processing library for Node written entirely in JavaScript, with zero native dependencies. If you're using this library with TypeScript the method of importing slightly differs from JavaScript. Instead of using require, you must import it with ES6 default import scheme. If you're using a web bundles (webpack, rollup, parcel) you can benefit from using the module build of jimp. Using the module build will allow your bundler to understand your code better and exclude things you aren't using. If you're using webpack you can set process.browser to true and your build of jimp will exclude certain parts, making it load faster. The static Jimp.read method takes the path to a file, URL, dimensions, a Jimp instance or a buffer and returns a Promise. In some cases, you need to pass additional parameters with an image's URL. -
